With the addition of elevation and land use and land cover data, we can show population density on a map much more effectively than if we simply color census areas. The resulting maps should allow better planning, especially in highly developed areas.

To expand data functionality and capabilities for users of The National Map of the U.S. Geological Survey, data sets for six watersheds and three urban areas were converted from the Best Practices vector data model formats to Semantic Web data formats.

Clearinghouse for the description and availability of multiple geospatial datasets relating to Alaska from many federal, state and local cooperating agencies under the coordination of the Alaska Geographic Data Committee.

Website for the Columbia Environmental Research Center with links to staff, publications, databases, field stations, and projects including those on the Rio Grande, burrowing owls, sea turtles, and geospatial technology.

Web site for an Internet Map Service (IMS) serving base cartographic data, USGS data, science applications and real time modelling analyses for the Columbia River basin using geospatial analysis technology.

GIS data set from the USGS National Landslides Hazards Program showing major landslide events in the United States and Puerto Rico with metadata. Map layer can be downloaded in shapefile format or SDTS format.

Geographic Analysis and Monitoring Program (GAM) conducts studies about land surface change, environmental and human health, fire and urban ecology, and natural hazards to help decision-makers in land-use planning and land management.

Fact sheet describing the value of The National Map designed as a network of digital databases that will provide a consistent national geographic data framework in responding to natural hazards and human-induced disasters.

Complex geographic information can be analyzed with mathematical models to show us the spatial patterns of human building, vegetation growth, and other landscape characteristics that may result from environmental changes we may expect in the future.

Quantifies the landscape changes and consequences of natural gas extraction by digitizing indications of disturbance on NAIP aerial photographs and using these with the NLCD to show land use-land cover change.

Home page for National Wetlands Research Center's (NWRC) Spatial Analysis Branch (SAB), which uses state-of-the-art technology to assist the work of natural resource managers with spatial data and computerized analysis techniques.

Homepage describing The National Map, which will produce a seamless, continuously maintained set of public domain geographic base information, with links to map viewer, pilot projects, reports, fact sheets, and national atlas.
